Design and analysis of high reflection surfaces and polarization rotators using periodic strong chiral–metamaterial stacked structures

Abstract

In this paper, it is proposed that high reflection surfaces and polarization rotators can be designed using planar stratified metamaterials (MTMs). For this purpose, structures used in design are composed of strong chiral, dielectric, double negative, chiral nihility, and single negative MTM slabs. To investigate these multilayered structures, reflection and transmission coefficients are analytically computed using transfer matrix method. The expressions depend on frequency, angle of incidence, optical width of slab, and material parameters. The structures are tested for numerical values and then optimized results are presented. For each case, structure is composed of odd number of infinite length slabs. These structures can be used in filters, radomes, and polarization conversion devices.
